Trying to do a mosaic widefield.

This is about 20 minutes on the top section, and about 2 hours for the middle. Trying to capture some more now, but I think its turning out well

how on earth do you blend 2 images like that without getting a line?

[GazOC]

On Imerge its the "feather" option.

[RichieJarvis]

Hi Richie' nice one great colours in the picture.Taff

You could either use 'feather' in PhotoShop or possibly make a layer mask from one image and blur the mask to get a smooth blend

If you have Noels Actions for Photoshop you could use the remove horizontal banding tool.

Well - heres another attempt at processing... A bit more data this time - it turns out that there is 6158 seconds of Ha data and 9282 seconds of OIII data, obviously thats shared across all the images in the mosaic. Still not happy with the central section, its not light enough, and I cannot seem to correct this.

I generated this by merging in iMerge for each channel, and then back into Photoshop to combine the colour channels, etc. I tried running Noel's Horizontal banding tool on it, but it didn't make much difference - this is the image with it applied.

Any more tips?

I am going to try reshooting the middle section, and continue expanding the mosaic over the winter, weather permitting...

Looks as though this is going to be a "good un"

Coming along nicely there Richie.....Not the easiest thing to do in the world trying to do a mosaic.......

I think I might have this mosaicing thing sorted - I re-did the processing in PS yesterday. The trick is that you have to select only part of the frame to get feathering to work

Anyway, I think it looks alot better now - just need to get more data - I mean how far out does that gas GO??!!
